Their understanding of sexuality is becoming more detailed.

By third grade, if not earlier, children are aware of sexual differences, gender roles and gender stereotypes. Many are eager to find out what they don't know, and they look to peers and media for information. They have a stronger self-image regarding their bodies and gender roles than ever before.

What you should do: Teach your child about sexuality, even if she doesn’t ask. Recognize that children this age might be shy about asking questions, but that they may actually be very curious.
